Application:
1.) micro levels of food contact at the edge of the M-&-F thread intersection line
2.) 212 F degrees is the duty temperature.
3.) Used to join and seal SST half inch pipe threads
4.) Ph of the contact fluid is about 5.2
It's a goofy way to get a bulkhead pass through into a pot of boiling fluid.
A nut that threads onto the pipe threads, an O ring, a coupler, and a nipple.
The coupler and nut and O ring go on the inside of the vessel where they effect a seal. It's the bulkhead fitting package sold & in the picture here:

I thought that it might be a real bonafide bulkhead fitting just from China. But it's not, it's just a jerry rig, using plumbing parts.
Anyway I have some of them and I can't quite get my head around how it seals. Yah I get the O-ring against the vessel wall, but as to the threads?
Lots of other people use these things. I've read their posts in brewing forums. They claim the fittings produce a leak free junction.
Yet when I dry fit it all together I find that there are "issues" obtaining full thread engagement. So I'm thinking instead of Teflon tape what about JB Weld?
Looking at the picture knowing what I just described what do you think?
